摘要： When a titanium oxide surface-treated with a titanate-based coupling agent is used as an external additive on the surface of toner particles, titanium oxides are likely to be aggregated with each other and aggregated titanium oxide particles are likely to fall off from the surface of the toner. As a result, since toner particles do not support a required amount of titanium oxide particles, poor charging of the toner may occur and fog increases. Therefore, when a toner for electrostatic latent image development comprises color particles containing at least a binder resin and a colorant, and titanium oxide, as an external additive, formed on the surface of the color particles, the titanium oxide being surface-treated with a titanate-based coupling agent containing 30% or less of a solvent soluble component, aggregation of titanium oxides can be reduced and stable charging of the toner can be achieved, and thus the resulting image is stable for a long period.
摘要翻译：当用钛酸酯类偶联剂表面处理的氧化钛作为调色剂颗粒表面的外部添加剂时，钛氧化物可能彼此聚集，聚集的氧化钛颗粒很可能从表面脱落的调色剂。结果，由于调色剂颗粒不支持所需量的氧化钛颗粒，所以调色剂的充电可能会发生并且雾化增加。因此，当用于静电潜像显影的调色剂包括至少含有粘合剂树脂和着色剂的着色颗粒和形成在着色颗粒表面上的氧化钛作为外部添加剂时，用氧化钛表面处理含有30％以下的溶剂可溶性成分的钛酸酯系偶联剂可以降低钛氧化物的聚集，可以实现调色剂的稳定充电，因此得到的图像长时间稳定。

摘要： A two-component binder-type magnetic carrier for developing agent comprising a magnetic powder and a binder resin. The carrier particles contain dispersed therein a release agent of the type of a metal soap and have abrasive or collapsible surfaces. By using the developing agent which contains this carrier, the magnetic powder peels off the carrier particle surfaces maintaining a controlled particle diameter and amount. Therefore, the carrier particles possess fresh surfaces at all times, whereby the occurrence of spent toner is effectively prevented and the charging amount of the toner is stably maintained.
